Purpose

ABS Modulator Unit:

It adjusts the hydraulic pressure applied to each caliper on the basis of the signals received from the Anti-lock Brake System (ABS) control unit. The modulator unit consists of the following sub-units.

- ABS Pump And Motor: Supplies high-pressure brake fluid to control the ABS operation.

- Accumulator: Stores high-pressure brake fluid in it.

- Pressure Switch: Detects the pressure in the accumulator and transmits signals to the ABS control unit.

- Solenoid Valves: Switches the ABS high-pressure passage according to the signals from the ABS control unit.

- Pistons And Related Parts: Receives the high-pressure brake fluid, and controls pressure to the calipers accordingly.
